3 Sea Eagle EOSS Sea Eagle EOSS (Electro-Optical Surveillance System) is an advanced electro-optical surveillance system optimised for automated maritime surveillance on all classes of vessel. The system provides 24 hour passive surveillance and target identification through the use of thermal imager and daylight TV camera sensors (the system can also be fitted with a low repetition rate laser rangefinder). Sea Eagle EOSS has been designed to provide a high level of automated operation, therefore reducing operator work load and training. 3

4 Key Features 24 hour passive surveillance through high performance thermal imager and TV camera Programmable azimuth scan sectors with automatic target detection Automated slewing to search radar contact indications Display of a panoramic view of the scanned sector with marked detected targets Automated capture of target snapshot images Automated slewing to radar contacts Automatic target tracking Target range indication with optional eye safe, low repetition rate laser rangefinder Designed to operate as a fully integrated element of a multifunction console based combat system The system has been designed to significantly reduce through life costs when compared to similar systems. This has been achieved by the following key elements: Reduced initial acquisition costs Lower ship impact through lower equipment mass and reduced ship s cabling Reduced logistics support commitments through increased equipment reliability and application Programmable processing elements Reduced training requirements through the employment of a high level of automated operation Further information regarding the system s associated integrated logistics support package can be found later in this document. 4

5 System Outline Sea Eagle EOSS uses an advanced electro-optical sensor suite to provide target acquisition and tracking 24 hours a day. The system employs sophisticated image processing techniques to enhance target detection and tracking. Electro-Optical Sensors The electro-optical sensors consist of a midwave thermal imager, colour TV camera and optional eye safe laser rangefinder. They have been selected to provide effective target detection, acquisition and tracking of typical naval surface targets.

Operation Sea Eagle systems have been designed to be controlled from either a dedicated operator s console or from a combat system s multifunction console. For dedicated applications a range of console configurations are available to suit different vessel layout arrangements and space limitations. 5

6 System Operation Introduction Sea Eagle EOSS is an advanced electro-optical surveillance system. It has been designed to be used as a high performance surveillance system for applications such as search and rescue, threat surveillance and blind pilotage. The system sensors, the performance of which is enhanced by the application of image processing techniques, can detect, acquire and track targets 24 hours a day. Sea Eagle EOSS has been designed to provide a high level of automated operation which reduces operator work load and training. Operation Sea Eagle EOSS has been designed to provide a high level of automated operation, therefore reducing operator workload which leads to improved performance under high stress conditions and lower training requirements. Surveillance, Target Acquisition & Tracking The Sea Eagle systems feature a video processing system that provides a high level of automation to the surveillance, acquisition and tracking functions. The operator interface is viewed through a high resolution display that presents the different video streams in a completely flexible layout, with onscreen presentation of ancillary data and semi-transparent video overlays for key user interface items. The system is normally configured with a baseline suite of display formats that can be adjusted to suit specific customer requirements. In the surveillance mode the system can perform a number of scan patterns with automatic detection of contacts. Scan patterns range from continuous 360 degrees to defined arcs, which are displayed as a continuous strip together with a plan representation of system contacts. A typical view is shown below: 6

7 Real time tracking of multiple contacts in the field of view enables the operator to assign contacts as targets to be engaged. A typical tracking display is shown above. The image above shows the system operating in tracking mode, showing the thermal imager in autotracking mode. 7

8 System Configuration Electro-Optical Director The Electro-Optical Director (EOD) is the only above decks assembly. It is a precision, gyro stabilised elevation over azimuth, gear drive unit fitted with three electro-optical sensors: Midwave (3-5 micron) thermal imager with zoom optics Colour TV camera with zoom optics Optional eye safe laser rangefinder All three sensors are environmentally sealed and can be changed onboard. They are fitted to the director using a precision dovetail unit that permits exchange of sensors without the need for a mechanical alignment procedure. The EOD is fitted with quick release covers that provide an outer level of weather protection for the sensors and contain outer optical windows and wiper units. System Processor Assembly This assembly performs a range of functions through its processing unit: Director control System interfacing and control Target detection and tracking Wide angle surveillance 8

9 Operator s Console Sea Eagle systems have been designed to be controlled from either a dedicated operator s console or from a combat system s multifunction console. The dedicated console is available in a number of configurations including a seated desk unit, and separate display and control panel for integration into a bridge console system. All console layouts feature ergonomic design that reduces operator workload and subsequently fatigue. System controls are configured to be intuitive in operation, helping to reduce training requirements. 9

10 Integrated Logistics Support Support Philosophy Sea Eagle systems have been designed to reduce through life costs with a holistic approach to logistics support. Based on experience gained in the support of a wide range of naval systems, the Sea Eagle support philosophy has been developed to achieve optimum availability of the systems. Maintenance Sea Eagle systems have been designed to require the minimum of periodic maintenance. Any maintenance that is required can be accomplished in the minimum time without the need for special tools or test equipment. Training Operator and maintainer training courses are available for a ship s crew and base support personnel. Courses can be adapted to meet specific training philosophies and styles and can be provided on electronic media to aid the assimilation of the training into a navy s own training regime. System Commissioning & Engineering Support A full programme of system commissioning is established with the customer and shipyard in order to ensure timely and effective installation, integration and introduction into service of Sea Eagle systems. Engineering services are available as required to supplement customer resources in the support of operational systems. Logistics Spares Onboard and base spares holdings are optimised in consultation with the Sea Eagle customer in order to ensure required system availability is maintained throughout the service life of the system. Repairs An optimised repair loop is established in consultation with each Sea Eagle customer in order to ensure the minimum repair turnaround time for defective LRUs. Configuration Management As with all Chess Dynamics products, Sea Eagle systems are subject to a detailed configuration management process. This ensures that throughout the service life of the system, spares and repairs support will be available when required. Much of the key functionality of the systems is provided through software implementation, which is the subject of continued development. Advances in performance through periodic software updates are offered to customers for incorporation into in-service systems in conjunction with an on-going support contract. 10
